From f2e761fdace257dd0411958efedb0e7af043c4f8 Mon Sep 17 00:00:00 2001 From: Daniel Oakley Date: Thu, 16 Jun 2022 11:07:46 +0100 Subject: [PATCH] media: vimc: enumerate data link entities for clarity The data_links array was hard to read and understand. By implementing enumerated vimc data link entities, clarity has been improved when defining data_links. This therefore should help new programmers to understand the codebase better. There is no functional change intended.
